您可以使用以下代码注册和取消注册远程通知。
Register RemoteNotification with bellow code..means Enable notification
使用下面的代码注册 RemoteNotification..意味着启用通知
//-- Set Notification
if ([[UIApplication sharedApplication]respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
{
// For iOS 8 and above
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
// For iOS < 8
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}
and Disable it with bellow code.
并使用波纹管代码禁用它。

Enable Push Notification (Setup from app):
启用推送通知（从应用程序设置）：
if #available(iOS 10.0, *) {
// SETUP FOR NOTIFICATION FOR iOS >= 10.0
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
if error == nil{
DispatchQueue.main.async(execute: {
UIApplication.shared.registerForRemoteNotifications()
})
}
}
} else {
// SETUP FOR NOTIFICATION FOR iOS < 10.0
let settings = UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil)
UIApplication.shared.registerUserNotificationSettings(settings)
// This is an asynchronous method to retrieve a Device Token
// Callbacks are in AppDelegate.swift
// Success = didRegisterForRemoteNotificationsWithDeviceToken
// Fail = didFailToRegisterForRemoteNotificationsWithError
UIApplication.shared.registerForRemoteNotifications()
}
Delegate methods to handle push notifications
处理推送通知的委托方法
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
}
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
// ...register device token with our Time Entry API server via REST
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
//print("DidFaildRegistration : Device token for push notifications: FAIL -- ")
//print(error.localizedDescription)
}
Disable Push Notifiacation:
禁用推送通知：
UIApplication.shared.unregisterForRemoteNotifications()
